Description

Technical Field

[0001] The utility model relates to the field of aluminum alloy plate processing, in particular to an elliptical plate stacking tool. Background Art

[0002] Aluminum alloy housings are an ideal casing material, highly favored for their lightweight and durable properties. These housings are commonly used in electronic equipment, automotive, aerospace, and other fields. They offer excellent performance, combining lightness with strength, effectively protecting internal electronic components while providing excellent heat dissipation. With the continued advancement of lightweighting in new energy vehicles, aluminum alloy battery housings are becoming the mainstream.

[0003] The aluminum alloy sheets used in the production of aluminum alloy battery casings are oval sheets. Due to the irregular shape of the oval sheets and the thickness of a single sheet being only 1.5mm, they are prone to uneven stacking. The higher the stack, the more likely it is to tip over, making it difficult to increase the stack height. Therefore, it is urgent to develop a tooling that facilitates the stacking of oval sheets. Utility Model Content

[0005] The locking mechanism is configured to lock the locking cam of the locking cam and the locking cam of the locking cam, wherein the locking cam has a first end fixed to the locking cam and a second end fixed to the locking cam, the second end of the locking cam being pivotally connected to the locking cam of the locking cam.

[0006] Furthermore, the front end of the limiting piece is movably sleeved on the positioning shaft, and the outer side of the positioning shaft between adjacent limiting units is sleeved with a shaft sleeve for limiting the limiting piece.

[0007] Furthermore, there are four positioning columns, and two positioning column clamping slots are arranged at intervals on each of the limiting slots.

[0008] Furthermore, the four positioning columns are respectively inserted into the corresponding positioning column slots and extend from the bottom limit plate, and the positioning columns are tightly fitted with the corresponding positioning column slots to form a U-shaped frame structure supported by the positioning columns.

[0009] Furthermore, the locking mechanism includes a positioning pin and a pin hole. The pin hole is provided on each of the limiting plates. The position of the pin hole is limited to being concentric when each of the limiting units clamps the elliptical plate. The positioning pin is inserted into the pin hole.

[0010] Furthermore, each of the limiting plates located on the same side is fixedly connected to a connecting plate, and the locking mechanism includes a positioning pin and a pin hole. The pin hole is provided on one or more limiting units located at the top, and the position of the pin hole is limited to the concentricity of the pin holes when each of the limiting units clamps the elliptical plate, and the positioning pin is inserted into the pin hole.

[0011] The elliptical sheet stacking tool implemented by this utility model has a space for accommodating the elliptical sheet by enclosing the opposing limiting grooves when the limiting plates are close to each other. The positioning columns position the sides of the elliptical sheet, and the locking members lock the limiting plates of each limiting unit, thereby limiting the stacked elliptical sheets and preventing them from tipping over during stacking. It has a simple structure, is easy to process, and improves the efficiency of elliptical sheet stacking. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 2 This is a schematic top view of the structure of the elliptical sheet stacking tooling described in an embodiment of the present utility model excluding the positioning columns and locking parts. DETAILED DESCRIPTION

[0014] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0015] like Figure 1 and Figure 2As shown, an elliptical piece stacking tool is shown, which includes a positioning shaft 1, four positioning columns 2 and seven groups of limiting units 3 for clamping elliptical pieces 10, each of the limiting units 3 is hinged on the positioning shaft 1 at intervals from bottom to top, and the limiting unit 3 includes two limiting pieces 31 that can be opened and closed relative to each other, each of the limiting pieces 31 has a limiting piece head end 311 and a limiting piece end 312, the limiting piece head end 311 is movably sleeved on the positioning shaft 1, and the limiting piece end 312 is a free end, and the two limiting pieces 31 are pieced together to form a U-shaped structure, and the outer side of the positioning shaft 1 between adjacent limiting units 3 is sleeved with a shaft sleeve 4 for limiting the limiting piece 31, and each limiting piece 31 on the same side is connected to a connecting plate 5 is fixedly connected; arc-shaped limiting grooves 313 are respectively provided on the opposite surfaces of the two limiting pieces 31, and when the two limiting pieces 31 are close to each other, the limiting grooves 313 relative to each other enclose the accommodating space of the elliptical piece 10; the positioning posts 2 are arranged in parallel, and two positioning post slots 314 are provided on each limiting groove 313 at intervals, and each positioning post 2 is sequentially inserted into the corresponding positioning post slot 314 and extends from the bottom limit piece 31, and the positioning posts 2 are tightly fitted with the corresponding positioning post slot 314. The limiting unit 3 is also equipped with a locking mechanism for preventing the two limiting pieces 31 from being displaced when the two limiting pieces 31 are relatively closed in place.

[0016] Furthermore, the locking mechanism includes a positioning pin 6 and a pin hole. The pin hole 315 is provided on the three groups of limiting units 3 at the top. The position of the pin hole 315 is limited to the concentricity of the pin holes 315 when each limiting unit 3 clamps the elliptical piece 10. The positioning pin 6 is arranged in the pin hole 315.

[0017] During assembly, the two limiting plates are first brought into relative position, the positioning pin is then inserted into the pin hole, and finally the four positioning posts are snapped into the corresponding positioning post slots to complete the assembly of the elliptical sheet stacking tool. When stacking is required, the elliptical sheets are sequentially placed between the four positioning posts. The positioning posts are tangent to the four points of the elliptical sheets to achieve positioning. The elliptical sheets can then be stacked and aligned. The positioning pin is then pulled out, and the elliptical sheet stacking tool is separated from the stacked elliptical sheets to proceed to the next stacking operation.

[0018] The thickness of each limiting piece of the present invention can be set as needed, and the U-shaped frame structure formed by each limiting piece can be placed on the ground or on two pads, but the thin piece design can reduce its own weight and facilitate the movement of the entire tooling; the number of the positioning posts is not limited to that shown in the embodiment, and can also be two. The positions of the two positioning posts can be when the two limiting pieces are relatively closed in place, the two positioning posts are located at the two ends of any diagonal of the inscribed rectangle of the elliptical piece, or can be arranged relative to each other on one side close to the positioning axis, but four positioning posts can be stacked more quickly and neatly; the limiting pieces located on the same side can be connected into one by a connecting plate, or can be connected into one by a latch, and the same side can be connected into one by a connecting plate. After the limiting pieces are connected as one, they are not only convenient to open and close, but also the pin holes can be opened only on the top few limiting units, and then the positioning pins can be inserted into the pin holes when the two limiting pieces are relatively closed in place to prevent the two limiting pieces from displacement; the positioning columns and the positioning column slots are not limited to a tight fit, but can also be a clearance fit, and only when the positioning columns support the entire tooling, the positioning columns and the positioning column slots need to be tightly fitted; the hinged structure of the limiting unit and the positioning shaft is not limited to that shown in the embodiment, and a loose-leaf can also be installed on the positioning shaft, and then the two limiting pieces of the limiting unit can be fixed to the loose-leaf respectively, as long as they can be relatively opened and closed.
